Axiom

Overview

Axiom is a large set of skills, agents and commands that give AI coding assistants detailed knowledge of Swift development for Apple's operating systems. It aims to prevent problems such as data loss from bad migrations, memory leaks and stuck xcodebuild processes. It's for Apple platform developers using Claude Code and other agents.

Features

• 285 skills covering UI, data, concurrency, performance, networking, accessibility and more
• 42 agents that scan for issues such as memory leaks, concurrency violations and build problems
• 17 commands for audits and diagnostics, such as /axiom:fix-build and /axiom:analyze-crash
• axbuild, a built-in build and test runner
• Captures simulator console output and triages .ips, MetricKit and .crash reports
• Skills activate automatically from your questions

Requirements

The source doesn't list any requirements, so check the project's own docs before you install.

Install

1. Claude Code: add the marketplace, then search for axiom in the plugin list

   /plugin marketplace add CharlesWiltgen/Axiom

2. Pi terminal agent

   pi install git:github.com/CharlesWiltgen/Axiom

3. Cursor has a native plugin; VS Code, Gemini CLI and others can use the MCP setup guide; Xcode has its own integration guide

Example

Ask your agent "How do I fix Swift 6 concurrency errors?" or run /axiom:audit memory to scan for leaks.
